The luminescence properties of M ' type of YTaO4 : Eu

A series of Eu3+ doped of M' type of yttrium orthotantalate Y1-xEuxTaO4(x = 0-0.30) was sythesized. The influence of activator concentration on luminescence properties was studied in detail. The strong evidence from excitation spectra, emission spectra and diffusive reflection spectra of this system shows that there is energy transfer from TaO43- to Eu3+ via the charge transfer and spectral overlap.Chemistry, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)8ARTICLE3226-2311
